Title: Improvements in player pianos
Filed: 1920-09-25
Abstract: 173,076. Morley, E. R., Morley, F., and Dawson, H. R. Sept. 25, 1920. Player-pianos; expression-controlling. - The hammer rail 3 and half-blow stick 1 are connected through a spring 6 to a bellows 4 communicating with the exhausters of the playing mechanism and through a. cranked lever 9 to a hand-operated lever 7. The piano normally plays pianissimo when the player mechanism is in use owing to the collapse of the bellows 4, which causes the half-blow stick to move upwardly. Actuation of the hand-lever 7 causes the bell-crank lever 9 to retract the half-blow stick 1 against the action of the spring 6, thereby withdrawing the hammer rail 3 and the hammers resting thereagainst, from the strings 10.

Title: Electric hammer drill
IPC: B25D16/00
Filed: 1972-06-15
Abstract: 1364961 Portable drill HILTI AG 15 June 1972 [21 July 1971] 27951/72 Heading B3C [Also in Division B4] A rotary percussive drill, including an electric motor 1 which provides drive for means for rotating a tool 19 and for means for applying axially directed impacts to the tool, is provided with means whereby the rotary drive to the tool 19 can be disengaged so that only impacts are applied to the tool. The tool 19 is received in a holder 18 for rotation therewith and axial movement relative thereto, and the holder is rotatable with cylinder 14 housing a hammer piston 16 and a drive piston 15. Rotation of the cylinder 14 is effected by means of a sleeve 12 provided with gear teeth keyed to the cylinder for rotation therewith but movable axially relative to the cylinder and biased by a spring 23 towards a pinion 11 driven by the electric motor 1 which also effects reciprocation of the drive piston via a crank arrangement. Movement of the sleeve 12 against bias of spring 23 so as to disconnect its teeth from pinion 11 is effected by rotation in one direction of a cylindrical element 28 provided with an eccentric pin 27 engaging in slots 25a, 26a in a slide 25 and a blocking element 26 respectively. Such rotation from a first position (i.e. that of Fig. 1) to a second position (Fig. 3, not shown) causes the slide 25 to move, via a slidable sleeve 24, the sleeve 12 against the spring 23 and out of engagement with the pinion. In this second position manual rotation of the tool 19 is possible. Further rotation of the element 28 in the one direction from the second position to a third position (Fig. 5, not shown) moves the blocking element 26 to a position in which its teeth 26b engage the teeth on the sleeve 12. In this third position the teeth on the sleeve 12 are still out of engagement with the pinion and the tool is also prevented from being manually rotated. A spring biased detent 30 is engageable in recesses corresponding to the first, second and third positions so that the element 28 can be held in a selected one of those positions.

Title: Improvements in or relating to compensated feed weighing machines
Inventor: SIMON WILLIAM GEORGE
IPC: G01G19/00
Filed: 1952-11-07
Abstract: 743,530. Automatic weight control systems. SIMON & SONS Ltd., R. Nov. 4, 1953 [Nov. 7, 1952], No. 28122/52. Class 38 (4). [Also in Group XVIII] In an automatic feed weigher of the type compensating for the suspended material at cut-off, the compensation (obtained either by loading the weighbeam or by adjusting the rate of feed) is automatically corrected after each weighing operation by a reversible electric motor. Material from an automatic feed, e.g. an endless conveyer driven electrically, or an electric vibrator or an electrically controlled gravity feed, is delivered to the weigh-pan 2, Fig. 1, suspended from a weighbeam 1 and weighed against a weight 3 on a rod 4. The pan 2 has a hinged delivery door 5 operable by a solenoid 12 via, levers 11, 10, pin 9 on sector 7, and lever 6. As the pan 2 fills and the rod 4 rises, a projection 20 on the weight rod 4 trips a bell crank 18 allowing a spring 17 to rotate an arm 16 and with it a shaft 124, thereby actuating a timing switch 2S, and, through a lost-motion linkage 15, 14, a feed control switch 1S. The bell crank 14 also rotates a shaft 122 (normally straight but shown curved for clarity) to open the hopper discharge interlock 22. The weight rod 4 also has a lug 21 for engaging a spring- loaded compensating bell crank 35 freely mounted on shaft 124. The normal weighing sequence is as follows. The timer switch 2S, Fig. 6, closes first, and energizes a motor T operating three cam-actuated mercury switches 27MS, 28MS, 29MS, Fig. 5 (not shown). The switch 27MS is a holding-in contact for switch 2S; switch 28MS energizes the automatic compensating device (see below); switch 29MS energizes the delivery door operating solenoid 12. Meanwhile switch 1S has opened to stop the feed motor 45, and the interlock 22, Fig. 1, now rides on the top of cam 7 to prevent switch 1S from being reclosed until the delivery door has roclosed. The compensating ball crank 35 is tensioned by springs 33, 34 which are adjusted by a screw and nut. operated by a reversible motor 30. This is controlled by a reversing switch 40S actuated by a projection 41 on the weight rod 4, in accordance with the actual (uncompensated) weight of material in the weighpan; because the rod 4 will have risen clear of the compensating bell crank 35 (which is held by a stop 37). Thus in accordance with any error in the actual weight delivered, the motor 30 adjusts the tension on the compensating springs 33, 34 during the period that the timing switch 28MS is closed. In a modification, Fig. 7 (not shown), the motor 30 adjusts a resistor in series with a vibrator conveyer instead of adjusting the compensating springs, and in a further modification, Fig. 8 (not shown), a weight may be adjusted along a balance compensator arm connected to the weigh beam. A counter for the number of weighs may be operated by the bell crank 14.

[Also in Division F1] A shipping container 1, Fig. 1, suspended from a crane by a cable 5 and a swivel 4 attached to a frame 3 is rotated when a weight 6 is turned about its vertical axis by an electric motor 9 and a clutch 7, 8. In a second embodiment, Fig. 2, two masses 10, 11, with wings 14 which form air brakes, are respectively connected to the rotor and the stator of a motor 12. The masses tend to rotate at equal speeds in opposite directions and brakes 15 are provided to permit the container to be turned in the desired direction. By rotating the axis of the masses the gyroscopic effect may be used to turn the container. Fig. 4 shows a radial fan 17 surrounded by two axially displaceable rings which deflect the stream of air tangentially to produce rotation either clockwise or anticlockwise depending which deflector is selected. Radial reaction forces, e.g. for damping oscillations of the load, are provided by circumferentially movable deflector 22. In Fig. 6, two fans with deflectors 20, 21 are separately driven at different speeds by motors 24, 25. Radial deflectors 26 are provided.

Abstract: 1352886 Screening machines BUEHLER AG Gebp 16 June 1971 [17 June 1970] 28198/71 Heading B2H A screening machine comprises a housing 1, Fig. 1, in which is mounted a tubular screen 7 with its ends secured to the housing at 9, 10 and a rotor 3 having vanes 5, Fig. 3, arranged within the screen and connected to drive elements 33, 35-37, the screen being connected, between the regions where it is secured to the housing, with a positive oscillatory drive 21-23 movable relative to -the housing. The rotor shaft 2 is driven by an electric motor 37 through pulleys 33, 36 and a belt 35 which also drives a shaft 21 at a higher speed through a smaller diameter pulley. The shaft 21 is provided with eccentrics 22 on which are mounted connecting rods 23 at their end 24, the ends 26 of the connecting rods being connected to a tubular rod 27, Fig. 5, secured to the housing 1 by hollow rubber springs 28. Alternatively, the ends 26 of the connecting rods are connected to an eccentric shaft parallel to and rotating synchronously with the shaft 21. Counterweights are removably and adjustably secured on the shaft 21. Each connecting rod has a rigid entrainment surface 29 in contact with half the periphery of the screen, the other half being surrounded by a stirrup 30 fastened to the connecting rod 23. Supporting rings 31 are arranged internally of the screen at the entrainment regions. The housing 1 is supported by rubber blocks 18 on a frame 19 which may be insulated from the ground by further rubber blocks. In operation, product to be sifted, e.g. flour, is fed through an inlet 12 into the screen 7 where it is thrown outwardly by the vanes 5 and is conveyed by the vanes along the screen. The vanes also effect cleaning of the screen. The finer particles pass through the screen into hoppers 15, 16 and coarser particles are discharged into a hopper 13. The eccentric shaft 21 may be constructed as a crankshaft. The screen 7 may be made of nylon or wire gauze. In a modification, Fig. 7 (not shown), the eccentric shaft (21) is mounted in a bearing housing (43) on top of the housing 1 and has an eccentric (22) which, through a connecting rod (45) extending through a passage (47) in the housing 1, drives the connecting rods (23) which are connected fast to one another by a tube (46) and which are arranged vertically. The discharge end of the housing is closed by a cover (52) in which the discharge hopper 13 is formed and which is connected as a unit with both ends of the screen so that the screen can be removed from the machine without dismantling the drive.
